Thursday on Morning Edition, USA Today's Christine Brennan made the case — as other observers have — that soggy conditions at Merion mean there could be some extremely low scores this weekend. Basically, the thinking is that the greens will be wet and soft. So, Brennan said, players "will be able to play target golf." Shots they aim at the holes will hit the greens and roll very little, if at all.

Wednesday on ESPN's Pardon the Interruption a guy who has won a U.S. Open dismissed such talk. According to 1973 Open champ Johnny Miller, who's now an analyst for NBC and The Golf Channel, "this course has always been underestimated" and the players are going to find it's very difficult.

The rough along the fairways, Miller said, "is the toughest rough that these guys — these young guys — have ever seen" because it's high and dense. And he doesn't think balls hit to the greens will necessarily stay near where they land. Wet conditions also tend to add to the amount of spin put on the balls when they're struck. "The backspin — because everything's wet — the guys are hitting near the pin and it's spinning back 30 feet," he said.

Finally, Miller said the course has "so many hard holes ... seven holes that are really, really hard ... maybe even eight."

Who's right? NBC-TV and The Golf Channel are doing the broadcasts if you're anxious to see.
